Error: Item has already been added. Key in dictionary: “4” Key being added: "4"
Line 40

Can someone help

Dear JTaylor,

Please, could you send your ppt to the powerpoint@aspose.com.
I will check what is wrong.

Dear JTaylor,

ppt has 2 problems.

  1. Metafiles in the presentation. It’s supported now.
    Please download new release Aspose.PowerPoint 1.1

  2. MS Charts. It’s not implemented yet.
